[client] Deduplicate SSH PTY session setup and host key verification

Extract the identical PTY session setup shared by the wasm and Android
terminal clients into ssh.StartPTYSession, and move the stored-key host
verification onto the engine so the embed client delegates and the
Android client passes the engine directly as HostKeyVerifier.
